I'm not really there yet, but when I left a Spanish-speaking country, it was a shift to be using English with the attendants on the (American) airline.  Likewise leaving Japan after a few months for Australia.  I do have arbitrary moments of using 'hai', 'da', or 'si' instead of yes.  I particularly like 'nyet' for no, perhaps because it sounds like "not yet" too.
